Abstract
The invention relates to the technical field of satellite application, in particular to the field of detection of satellites. In order to overcome the defects of the traditional measurement method, the invention provides a method for indirect length measurement through an AUTOCAD (Autodesk Computer Aided Design) so as to eliminate the limitations of a ruler, a vernier caliper, a micrometer caliper and other measurement tools for indirect length measurement. In a technical scheme provided by the invention, a digital camera is adopted to shoot a real object, a ruler is placed nearby an object to be measured and is used as a length standard during shooting, the ruler and an element to be measured are located on the same plane in parallel, then a photo is imported into the AUTOCAD and is zoomed out or in by taking the ruler as the standard, and size marking is carried out on the element to be measured so as to realize the indirect measurement on the length, the distance, the displacement and other aspects on shape, position and size. By adopting the method in the invention, the advantages of high measurement precision superior to 0.1mm, simple measurement method, and easiness for implementation are achieved, and the operating requirement for satellite detection is met.
Description
Technical field
The present invention relates to the satellite application technical field, be specifically related to the satellite detection range.
Background technology
Conventional satellite relates to the detection of morpheme size aspects such as length, distance, displacement in detecting, and generally adopts survey instruments such as ruler, vernier caliper, micrometer caliper directly to measure.If but the testee profile is irregular, the operating space is narrow and small, such as public hinge and female gap of cutting with scissors in the measurement solar battery array hinge, the traditional measurement method that adopts above-mentioned survey instrument directly to measure just can't be implemented, and it is big by the range estimation measuring error, and the human factor influence is big, greatly reduce measuring accuracy, can not satisfy the request for utilization that satellite detects.
Summary of the invention
In order to satisfy the request for utilization that satellite detects; The objective of the invention is to overcome the deficiency that existing measuring method exists, propose a kind of method of carrying out the indirect measurement of length, solve survey instruments such as adopting ruler, vernier caliper, micrometer caliper and carry out the directly limitation of measurement of length by AUTOCAD.
In order to reach the foregoing invention purpose, the technical scheme that the present invention is adopted for its technical matters of solution is:
A kind of method of carrying out the indirect measurement of length by AUTOCAD, it is characterized in that: adopt digital camera that material object is taken pictures, near testee, place when taking pictures one ruler as length standard, ruler is in same plane and parallel with the element that needs to measure, then photo is imported AUTOCAD, be that benchmark carries out dwindling of photo or amplifies with the ruler, and the element that need are measured carries out size marking, realize the indirect measurement of morpheme size aspects such as length, distance, displacement.
The invention has the beneficial effects as follows: (1) can realize the indirect measurement of morpheme size aspects such as length, distance, displacement in the satellite detection; (2) measuring accuracy height, measuring accuracy is better than 0.1mm, satisfies the request for utilization that satellite detects; (3) measuring method is simple, is easy to realize; (4) cost is low.
Description of drawings
Fig. 1 utilizes the present invention to public hinge in the solar battery array hinge and female hinge clearance measurement synoptic diagram.
Be labeled as among the figure: 1. public hinge, 2. scale, 3. spool, 4. female hinge, 5. cable pulley, 6. launch spring.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The solar battery array hinge mainly is made up of public affairs hinge, axle, female hinge, cable pulley and expansion spring etc.Described public hinge interconnects by axle with female hinge.In order to detect the assembly quality of solar battery array hinge, the gap of measuring between public hinge and the female hinge is to close one of key control operation.
Near hinge, place one ruler as length standard, ruler is in same plane and parallel with described axle, adopt digital camera that hinge and ruler are taken pictures, then photo is imported AUTOCAD, 1mm is that benchmark carries out dimensional standard with the minimum measurement of ruler scale, comparison film dwindles or amplifies until standard size consistently with physical size, and the public hinge of mark is 1.01mm with gap between female the hinge at last, differs only 0.01mm with design load 1.00mm.
Measurement with female hinge gap proves through public hinge in the solar battery array hinge, the present invention can realize the indirect measurement of morpheme size aspects such as length, distance, displacement in the satellite detection, and measuring method is simple, is easy to realize, measuring accuracy is better than 0.1mm, satisfies the request for utilization that satellite detects.
